Humble Bundle has unveiled The Humble Indie Bundle 3. As with previous bundles, purchasers are asked to pay whatever price they feel is fair for the bundle, with some of the proceeds going to the Child's Play and EFF charities. This time the games in the collection consist of And Yet It Moves, Cogs, Crayon Physics Deluxe, Hammerfight, and VVVVVV.

Crayon Physics Deluxe is a 2D physics puzzle / sandbox game, in which you get to experience what it would be like if your drawings would be magically transformed into real physical objects. Solve puzzles with your artistic vision and creative use of physics.

Cogs is an award-winning puzzle game for the PC, iPhone, iPad, Mac and netbook. Immersed in a steampunk world with stunning visual design, Cogs players build an incredible variety of machines from sliding tiles. With 50 unique levels and three gameplay modes, we've packed in hours of entertaining, addictive fun.

In VVVVVV, the player controls Captain Viridian, who is lost in an alternate dimension, in search of the missing members of his spaceship's crew. Instead of jumping, the player is able to control the direction of gravity, allowing Captain Viridian to flip between the floors and ceilings of the environment.

Hammerfight is about 2D battles of flying machines equipped with various slashing, piercing and blunt weaponry.A unique combat system is based on realistic physics simulation, and it ties the movements of the rider to the movements of your mouse. As you wave the mouse, your rider swings his warhammer, smashing the foe into the wall!

In addition to the Jump ‘n Run concept, the core mechanism of And Yet It Moves is the ability to rotate the world in intervals of 90 degrees. The player has to apply the physical consequences of rotation with adroitness and a sense of orientation.
